As a high school or undergraduate Physics teacher, you can use this set of computer-based tools to help you in teaching Planck’s Law, the Stefan-Boltzmann Law, and Blackbody Radiation.
This lesson plan allows students to visualize the emission spectra associated with particular temperatures, to understand how Planck’s Law can be used to plot blackbody curves of objects with different temperatures, and to learn the relationship between temperature and peak wavelengths in the electromagnetic spectrum. The activity also introduces the topic of planetary temperatures of objects in the solar system and shows the greenhouse effect of Earth’s atmosphere.
Thus, the use of this toolkit allows you to integrate the teaching of a climate science topic with a core topic in Physics.
Use this lesson plan to help your students find answers to:
- 1. How can Planck’s Law be used to plot blackbody curves of objects at different temperatures?
- 2. How can the Stefan-Boltzmann Law be used to calculate the surface temperature of blackbodies?
- 3. Why does the surface temperature of Earth increase due to the greenhouse effect of the Earth’s atmosphere?
